Testing a Hypothesis of 12S rRNA Methylation by Putative METTL17 Methyltransferase.
Mitochondrial ribosome assembly is a complex multi-step process involving many additional factors. Ribosome formation differs in various groups of organisms. However, there are universal steps of assembly and conservative factors that have been retained in evolutionarily distant taxa. METTL17, the object of the current study, is one of these conservative factors involved in mitochondrial ribosome assembly. It is present in both bacteria and the mitochondria of eukaryotes, in particular mice and humans. In this study, we tested a hypothesis of putative METTL17 methyltransferase activity. MALDI-TOF mass spectrometry was used to evaluate the methylation of a putative METTL17 target - a 12S rRNA region interacting with METTL17 during mitochondrial ribosome assembly. The investigation of METTL17 and other mitochondrial ribosome assembly factors is of both fundamental and practical significance, because defects in mitochondrial ribosome assembly are often associated with human mitochondrial diseases.
期刊介绍：
Acta Naturae is an international journal on life sciences based in Moscow, Russia.
Our goal is to present scientific work and discovery in molecular biology, biochemistry, biomedical disciplines and biotechnology. These fields represent the most important priorities for the research and engineering development both in Russia and worldwide. Acta Naturae is also a periodical for those who are curious in various aspects of biotechnological business, innovations in pharmaceutical areas, intellectual property protection and social consequences of scientific progress. The journal publishes analytical industrial surveys focused on the development of different spheres of modern life science and technology.
Being a radically new and totally unique journal in Russia, Acta Naturae is useful to both representatives of fundamental research and experts in applied sciences.
